Abstract

Flange vertical buckling is one of the collapse types of an I‐shaped steel girder under bending, and has been considered to occur only in girders with very slender web plate. However, in authors’ experimental test on the hybrid steel girders, the flange vertical buckling was observed in one of the test models. In this paper, a numerical analysis is made on flange vertical buckling in a hybrid steel girder. The aim of this paper is, as a first step on the research on flange vertical buckling of hybrid steel girders, reproducing and realizing the flange vertical buckling with the numerical analysis, and to study the basic behaviour of flange vertical buckling of the hybrid steel girders.
